I live in the Norhtern area of South Australia, sad to say I dont see so many up here.. Its all country and commonwhore town, but I have been to the adelaide hills on one of the more recent AE86 cruises in Adelaide.. I would have to beleive the amount of import cars are in Adelaide and the southern hills for the fact of the mountains and windy roads are there, I had a blast in my Sprinter when I went there but havent been since as ive no time and my cars recently been defected..
Mind you I have been to as far as elizabeth and salsbury a few times, the amount of R32 and R33s is crazy in these areas!
I dont know much of other states road worthy leniance, is S.A. such a tough state? Or is it slack here?
